AB: We will present analysis of infrasound signals of some recent high explosive (HE) events. The events include a recent explosive test, Watusi, at the Nevada Test Site (NTS) as well as some small explosions done under a Department of Defense (DOD) program, also at the NTS. Watusi, with a charge weight of 19 tons, was recorded at four Los Alamos National Laboratory/Department of Energy (LANL/DOE) infrasound arrays. Summary results will be presented, followed by a comparison to earlier HE data recorded by LANL arrays. These earlier data were from larger tests undertaken by the former Defense Nuclear Agency, now Defense Threat Reduction Agency. The Watusi data fit well with the earlier results for wind corrected amplitude versus scaled range. We also have recorded, from calendar year 2000 to the present, infrasound signals from 1000 to 2000 lb explosions executed at the NTS. These events were recorded at a range of 45 km by the LANL NTS array. These results show that detection at this range is fairly robust.
